Pseudoexfoliation (PXF) is a recognized risk factor for developing cataract, glaucoma and lens dislocation. PXF is also associated with increased risk of complications during cataract surgery due to poor mydriasis and zonular weakness. The aim of this study is to report the prevalence of pseudoexfoliation among Upper Egyptians attending the ophthalmology clinic of Assiut University Hospital.
A retrospective, chart review study conducted in the period from February 2002 to August 2009. A total of 7738 patients aged 40 years or older attending the general ophthalmic clinics were included in this study. A detailed evaluation including ophthalmic and general history, slit lamp biomicroscopy, intraocular pressure measurement, gonioscopy and dilated eye examination were performed. Patients with pseudoexfoliative material on the anterior lens surface and ⁄ or the pupillary margin in either or both eyes were labeled as having PXF.
Out of the 7738 patients included, three hundred twenty (4.14%) subjects had PXF. Mean age of PXF group was 68.15 years (SD 8.16, range 40-92 years). PXF was bilateral in 82.2% of cases. It was significantly associated with cataract, glaucoma and hearing loss. Of the PXF patients, 65% had cataract, 30.3% had glaucoma and 8.1% had hearing loss.
Pseudoexfoliation appears to be a common disorder in older individuals in Upper Egypt.
假性剥脱（PXF）是白内障、青光眼和晶状体脱位的公认危险因素。由于散瞳不良和悬韧带脆弱，PXF 还与白内障手术期间并发症的风险增加相关。本研究旨在报告在埃及上埃及就诊于 Assiut 大学医院眼科诊所的人群中 PXF 的患病率。
这是一项回顾性图表审查研究，于 2002 年 2 月至 2009 年 8 月期间进行。共纳入了 7738 名年龄在 40 岁或以上的在普通眼科诊所就诊的患者。对所有患者进行详细评估，包括眼科和一般病史、裂隙灯生物显微镜检查、眼压测量、房角镜检查和散瞳眼部检查。在一只或两只眼中，只要在前晶状体表面和 ⁄ 或瞳孔缘存在假性剥脱物质，就将患者标记为患有 PXF。
在纳入的 7738 名患者中，有 320 名（4.14%）患者患有 PXF。PXF 组的平均年龄为 68.15 岁（SD 8.16，范围 40-92 岁）。82.2%的病例为双侧 PXF。PXF 与白内障、青光眼和听力损失显著相关。在 PXF 患者中，65%患有白内障，30.3%患有青光眼，8.1%患有听力损失。
在埃及上埃及，假性剥脱症似乎在老年人群中较为常见。
